How to keep your computer clean 8

8. Use a firewall. You can find free versions for personal usage of Sygate, Outpost Firewall and Zone Alarm.
I know maybe it looks this is mostly for preventing attacks on your PC, but today's firewall software also keep a constant tracking of all applications that go online. This means that if you ever get infected with a virus for example, it can not connect to the internet unless you allow this. If this looks useless, think that there are many trojans that connect to remote sites and upload any personal data that can find (passowrds, e-mail account, credit card numbers, etc).
